  # WARNING: If you use this, make sure that your FreeRTOSConfig.h and port
  # does not rely on any statics inside of tasks.c. For example, you cannot use
  # PW_CHECK for configASSERT when this is enabled.

  # As a helper PW_THIRD_PARTY_FREERTOS_NO_STATICS=1 is defined when statics are
  # disabled to help manage conditional configuration. In addition a helper
  # pw_third_party_freertos/assert_config.h header is provided which correctly
  # sets configASSERT to use PW_CHECK or PW_ASSERT for you.
